The Scarpa chalk bag is an excellent find for £9.99 and comes with different colourways so that you will not have the same bag as the next person. The one I bought was the Fire/sun and it looks good and works well as a chalk bag because of the fleece interior and durable material. It also has a toothbrush holdall for added convenience. Note that it does not come with a strap and you will need one or use a carabiner to attach to the harness (which is what I do).
I use this for poledancing not climbing but it keeps the chalk away from things it shouldn't be on!
